Library of Congress (LC) Call Numbers are like an item's address to help you find where it lives on the shelf. Each letter stands for an academic discipline. In the image below, L is for Education, LD is for Individual Institutions - United States. Can you guess which institution is at LD 4363 .U55 2006?
To read a call number, read the number from left to right or top to bottom as follows:
Lastly, the shelf is organized from top to bottom in sections, so you'll zig-zag down each section 
to look for your call number before moving to the next section.
Bonus: You can also click the "Locate" option in LibrarySearch to see a floor map with the number of the shelf your item is on.

LibrarySearch offers a streamlined interface for finding books and other media that combines the collections of UO Libraries and Summit libraries.
Books can offer a chance to learn about a subject in-depth. Edited books can provide a chapter or chapters related to your topic. In addition to print books, the UO Libraries offers many ebooks that can be accessed remotely by current UO students and faculty.
To search:
If you want only books/videos/music in the UO Libraries system, change the search scope to "UO Libraries."
If you want books/videos/music in the UO Libraries system and the consortium of 37 colleges and universities in Oregon, Washington, and Idaho, select "UO + Summit." You can place a request for books within Summit using LibrarySearch. Requests generally arrive within 3-5 days.
If you want to broaden your search even further, use WorldCat to search beyond the UO Library and the consortium. These materials are requested through Interlibrary Loan and may come from any library. Books and AV items arrive within an average of 10 days. You can also request individual book chapters be scanned and sent to you. There is a link to WorldCat on the Libraries' homepage.
You can limit your search results by resource type using the search filters, usually on the left-side of the screen (or click on the filter icon if you are on a mobile device). Click on "Print books" and "eBooks" to limit your results to both types of books.
